LED bulb turns into flashlight

Clever LED bulb turns into flashlight when needed

LED bulbs are rapidly becoming mainstream, with prices going down and quality/performance going up. In fact, some cities are replacing over a hundreds of thousands of street lamps with LED models to save energy, increase safety, and reduce maintenance costs.

But that's not all the technology is good for. LEDs use so little power that it's possible to put a battery in the bulb and turn it into a flashlight when power is out. That's what designer Lin Guohui did, and his bulb (which you can see above) is sold by the Museum of Modern Art (MOMA).

Works and recharges in any standard E27 or E25 screw-in light fitting. When fully charged, extend the telescopic handle and use it as a flashlight up to 4 hours. It uses just 6 watts of power to produce light equivalent to a 40W incandescent bulb. The LEDs will last up to 60,000 hours. Charge minimum 5 hours.
